On Monday, the markets were mostly lower, as a deal between Sprint (S - Get Report)  and T-Mobile US (TMUS - Get Report)  was announced (see Jim Cramer's Sprint/T-Mobile Merger Is Crazy ... But Just Might Work), and Walmart (WMT - Get Report)  said it would sell its U.K. supermarket business. The Personal Consumption Expenditures price index rose 2% year over year in March, up from 1.7% in February. The 2% gain in the PCE met the Federal Reserve's inflation target.  

Here are three top takes from the columnists of Real Money and Real Money Pro, our premium sites for Wall Street professionals and active investors:

Jim Cramer: The Market Has Gotten Too Fickle to Maintain a Sustained Advance

"Leadership is so hard to come by in this market. We seem to gain and then lose it on a daily basis. Just think how often leadership has changed: we loved the banks, and then hated them, we loved the industrials, then hated them, we loved the soft goods, and then hated them. We loved FANG last week, now we have turned on it. We loved tech upside surprises, now they can barely hold on," writes TheStreet's Jim Cramer.

What does work? asks Cramer.

Evidence of a Bear Market Keeps Piling Up

"Is a bear market showing up? Certainly, some qualities of a bear have started to arrive," notes Real Money Pro columnist Robert Lang.

"The action last Tuesday might have indicated that we're ready to shift gears. We saw a downright nasty reversal that day, with higher volume levels and some very heavy selling," Lang adds, "Further, there was little buying of protection, which is often seen as a trait of bull markets. (Bear markets arrive unannounced.)"

5 Negatives That Are Hanging Over This Market

Real Money columnist James DePorre points out that "Many market players are growing concerned that a major market top is starting to form. There are hard core bears that have been anticipating that event for many years but now less dogmatic market participants are starting to worry that it is going to be a rough summer for the market."

"You don't have to be a fortune teller to think that the market has some issues. The evidence is right in front of our faces," says DePorre. Here are the issues that are causing concern.
